Description

Technical Field

[0001] The utility model relates to the technical field of welding machine structures, in particular to a welding mechanism. Background Art

[0002] Electronic components are basic elements in electronic circuits. Most common electronic components are welded on printed circuit boards, and there are also separately packaged electronic components. The current welding technology of electronic components is very complete, but after welding the electronic components, due to the physical properties of the welding material, spikes will appear on the top of the solder joints. When the welded workpieces are packaged and encapsulated, the spikes will scratch the packaging bag, which directly affects the efficiency and quality of the workpiece packaging.

[0003] The existing electronic component welding device needs to place the circuit board on the workbench and fix it. When the electronic components need to be welded on both sides of the circuit board, the clamping plate is pushed and clamped by a cylinder. When the outer diameter of the clamping plate is different, the clamping plate will be pushed by the cylinder. The force transition during the pushing of the clamping plate will cause a certain amount of wear on the side of the circuit board due to the impact, affecting the quality rate of the workpiece. Therefore, a welding mechanism is needed to solve the above problem. Utility Model Content

[0007] Preferably, the surface of the frame plate begins to have a through groove that is compatible with the processing table plate, and a silicone plate is embedded in the top of the inner wall of the frame plate through the installation groove. The through groove design on the surface of the frame plate can facilitate the translation of the frame plate on the surface of the processing table plate, which can form a clamping effect on the electrical components.

[0008] Preferably, a rail is connected to the top of the rack, and the rail is embedded in the bottom end of the processing table through a guide groove. The rail can be guided by the guide groove at the bottom end of the processing table, so that the rack can be stably moved and suspended.

When the height of the processing table is adjusted, the rack and the gear can be driven to rise synchronously to avoid meshing misalignment between the gear and the rack.

[0010] Preferably, a shaft cylinder is connected to the bottom end of the movable seat, and the shaft cylinder is embedded in the base through a guide groove. A threaded shaft is inserted through a threaded hole on the side of the shaft cylinder. One end of the threaded shaft passes through the base.

The L-plate seat is fixed to the side of the movable seat by bolts, and the locking bolt is rotated and moved in the threaded hole of the L-plate seat, thereby facilitating the pushing of the clamping block and controlling the degree of clamping tightness of the two clamping blocks on the movable column.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting up a fixed component, the protection and clamping of electrical components can be achieved. This device is embedded in the mounting groove of the frame plate through a silicone plate. By driving the motor shaft end to rotate, the polygonal inner shaft and the shaft sleeve cooperate to drive the gear to rotate. The gear can control the relative movement of the two racks, and then control the movement of the two frames to clamp the electrical components. At the same time, the silicone plate wraps both sides of the electrical components under force, which can effectively reduce the chance of wear on the electrical components during clamping and increase the probability of high-quality products.

[0015] 2. By setting the adjustment component, the displacement and lifting adjustment of the processing table surface can be realized. The device moves between the two clamping blocks through the movable column, thereby changing the height of the processing table, so that the processing table can be lifted, and then changing the lower limit height of the electrical components when placed. At the same time, the rotation of the threaded shaft can control the movement of the shaft tube in the guide groove of the base, and then the electrical components can be fine-tuned after clamping to facilitate welding.

The fixing component 5 includes two clamping components 55 arranged opposite to each other, and the clamping component 55 includes a rack 551, and the inner sides of the two racks 551 are meshed with gears 51 through teeth, and the outer sides of the racks 551 are connected to a frame plate 553.

[0024] A through groove matching the processing table 46 is formed on the surface of the frame plate 553 , and a silicone plate 554 is embedded in the top of the inner wall of the frame plate 553 through the mounting groove.

[0025] The top of the rack 551 is connected to a rail 552 , and the rail 552 is embedded in the bottom of the processing table 46 through a guide groove.

[0026] The bottom end of the gear 51 is connected to a polygonal inner shaft 52, and the bottom end of the polygonal inner shaft 52 is inserted into a sleeve 53 through a polygonal groove. The bottom end of the sleeve 53 is connected and fixed to the output end of the drive motor 54. The bottom end of the drive motor 54 is installed on the surface of the movable seat 41, and the top end of the gear 51 is rotatably connected to the processing table 46.

[0027] The bottom end of the movable seat 41 is connected to a shaft cylinder 47 , and the shaft cylinder 47 is embedded in the base 1 through a guide groove. A threaded shaft 48 is inserted through a threaded hole on the side of the shaft cylinder 47 , and one end of the threaded shaft 48 passes through the base 1 .

[0028] A movable column 45 is connected to the bottom side of the processing table 46 , and the movable column 45 is inserted between the two clamping blocks 43 through a through hole.

[0029] A locking bolt 44 is rotatably connected to the outer side of the clamping block 43 , and the locking bolt 44 passes through the inside of the L-plate seat 42 through a threaded hole, and the L-plate seat 42 is fixed to the side of the movable seat 41 by bolts.

[0030] The through groove design on the surface of the frame plate 553 can facilitate the translation of the frame plate 553 on the surface of the processing table 46, which can form a clamping effect on the electrical components. At the same time, the silicone plate 554 design of the mounting groove on the inner wall of the frame plate 553 can form an effective wrapping and protection effect on the sides of the electrical components during the clamping process, thereby reducing the wear of the electrical components during clamping.
